Answer:
B) 7v^3-15v^2-17v-3
Step-by-step explanation:
(v-3)(7v^2+6v+1)
7v^3+6v^2+v-21v^2-18v-3
7v^3+6v^2-21v^2+v-18v-3
7v^3-15v^2-17v-3
Answer: y= -x-5
Step 1: Determine which equation to change
Since we will be using the substitution method, we will need to substitute y from the bottom equation with information from the top equation. This will be the equation we change.
Step 2: Change the equation
Let’s rewrite the equation we will be working with.
3x+3y= -15
Our goal will be to get y alone on the left side. To start, let’s subtract 3x from both sides, leaving only 3y on the left side.
3x+3y= -15
3y= -3x-15
Now we need to get y completely alone by eliminating the coefficient of 3. Let’s do this by dividing each term by 3.
3y= -3x-15
y= -x-5
